I Tojqll V may concern.:

Be itzknown thatLGEoR'ea F. HUTCHINea Y citizen of the United States,residingatWorcester, in the countyof Worcester and. State ofMassachusetts, have invented new and useful Improvements in Shuttle-'BoxMotions 4for iooms, of; whichV the following isa specificaion.. r Myinvention relates to the shuttle-box molov tion of a loom, andparticularly to that class.

of shuttle-box motions in 'which the vertical movement of two ormorershuttle-boxes at.

one or-both ends of he loom is controlled by 'apattern-indicatingmechanism. I 5 The object 'of' my invention is toimprov upon the construction of shuttle-box motions of different typesas Ordinarily made, and more particularly. to provide j n'a set of coninections intermediate alever operated by the 20 pattern-chain surfaceand 'themovable shut-- tle-boxes at one or both ends of a loom twocranks, the first crank" the.'one nearer the pattern-surface, which inthis instance is the well-known?.vibrator-gear--driving or moving andlocking in position the other. or second crank nearer the vboxes and--each crank at' every nlovement'thereof moving from one extremeposition vto its other 'extrerneI position or its full .throw through anarc of sub- ,.30 -stantiallylo'ne hundred 'and eighty degrees.

In the accompanying drawings, 1 represen ts the loom sides, and2`theloom-arches.

`In Fig. -1 of the drawingsis shown a part of the Knowles box indicating'mcchanism issue Letters Patent'. No. 7,784 and comprisirgtheupper box cylinder-gear il, Ithe lower box cylinder-gear 5, thevibrator-levers 6, extending over and actuated by the pattern- ,shownand'described in United States Re' chain 7 on the ,pattern barrel orcylinder 7 on the shaft 7", which shaft also carries the pat-'teru-chain(not shown) of the harness-motion,

the vibrator-gears 8, carried on theelevers and forming cranks which ateach 'movement 2j Y 'y M448-, AVAILABLE este f from one-extreme positionto the other mov'e through an arc of substantially one hundred andeighty degrees in the usual way, and the.

vibratorfconnectors 9. y y

The two vibrator-connectors 9 are pivotally connected to the two leversor arms 10 and 10'. 'l` he lever 10 has a hub 10", loosely mounted on ashaft 11. The lever 10' has a hub 10"',

fast on the shaft 11 to cause said shaft to rockA with said lever, 10. i

The four movable shuttle-boxes 13 at the left-hand end of the loom inFig. 1 are sup ported on the upper end of a vertically-moving rod 14 andguided in the box-frame in the usual way. The rod 14 is adjustablysecured in this instance'at its lower end in a boss 15 on a stud 16,held in a giveway connection.

The giveway connection 17 in this instanceV 'consists of an upright part17', having a curved recess portion near its middle portion to receivethe stud 16 and forked at its'jlower end 17"' (see Figs. 1 and 4) toreceive the end of the box-lever 18,k which is pivotally attachedthereto. The part 17' of the giveway connection 17 has a boss 17n at itslower end for the box guide-rod-19 and also aboss 17" at its centralportion-for the guide-rod 19. The` box guide-rod 19 is attached `at itslower end to the rocker-iron 20 of vthe lay-sword 21 in the usual wayand at its upper end'to the box bearing or casing 22.l (See Fig. 2.)`The other part, 17, ofthe givewayconnection 17 is pivotally attached atits lower end to the part 17' and has a curved recessedportion at aboutits middleportion to receive the stud 16 on the hossl.` i -W l The upperend of the part 17" is connected to the part 17 and the two parts 'areyieldingly held together to holdl the stud 16 and cause the box-rod-M tomove upand down with the giveway connection, in this instance by aspiral spring 23, which is attached at one end to the part 17"'v and atlits otherend to a latch 24, pivoted on the'part 17'. (See Figs. 2 and3.) =f

When the latch A24 is in its normal position,

y the tension of the spring 23 acts to hold the the stud 17. 'lwosprings 23 may be used,`

if preferred, one on each side 'of the latch 24. The collari,earrying'the stud 16, is preferably loosely mounted on the'lower end ofthe box-rod 14:,.and by meansvfof the-two nuts 15' on the threaded endof the rod, one above. and one below the collar 15, said `collar may beadjusted up or down'on the rod 14 andsecured thereon toproperlyvpositionthe shuttle-boxes as desired. A spring. 14", (see Fig.

1,) attached at one end to a stationary part (not shown) and at itsother end toa flexible connectionfift, which 'passes over a 'pulleylmandisf'attaohed to thegiveway con'nection-17,-acts asa.couriterbalance,to theV weight of the shuttlefhoxes. .v 4

rifhe Ibox-lever 18, as before stated, is pivotally attached at one endto the lower end of the partv '17y of 'the giveway connection '17" thelower end of aconnector 25. end' of said connector 25 is piv-otaltt7attached to a crank'26, fast on one end of a shaft27,

and at its other end is pivotally attached .to`

The upper v mounted in bearings on a stand- 28 on the loom-frame. Gn theopposite end of the shaft 27 is fast a pinion 29, which meshes with theteeth 30' on the lower'end of a verticallymoving rod 30, the upper endof which is pivotally connected witha lever or arm 31, fast.

on the hub 10 of the lever 10.

The box-lever 18 intermediate its ends has the lower end of a connector32 pivotally attached thereto, (see Fig.` 2,) forming a movable fulcrumfor the lever 18. The upper end 'of the connector 32 is pivot-allyattached toa crank 33, fast on one end of a shaft 34, mounted inbearings on the loom-frarne. 0n the opposite end of the shaft 3e is fasta pinion 35, which meshes with the teeth 36 on a vertically-moving rodv36, the upper end of which is pivotally connected with a lever or arm37, having ahub 27' fast on the shaft 11.

A roll 39, mounted on a stud 38 on the frame 1, is located directly backof the toothedportion 'of the rods 30 and 36 to hold them in meshwiththe pinions 29 and 35, as shown in Fig. 2. n

I have described one box-lever 18 and its operating mechanism and partsconnected therewith, which forms a complete box-mo-A tion for one' setof shuttle-boxes at one end ofthe loom entirely independent of theboxrnotion for the Shuttle-boxes at the other end of the loom;

The several parts of the box-motion for the shuttle-boxes at the otheror right-hand end of the loom (shown in Fig. 1) correspond to and are ofthe same construction'and operation as the`parts of the box-motionalready described and shown at the left-hand end of theloom in Fig. 1and are designated by the same letters of reference-with theletter "a7added thereto.

'In order to connect the box-motion on the righthan'd endof the loomwith the vi bratorgears 8 ofthe pattern-indicating mechanism on theleft-hand end of the iooin at the upper part thereof, ltwo long rigidconnectors 9 are used, which extend back of` the arch 2. (See Fig; 1.

The operation of my improvements will he readily understood by thoseskilled inthe art.

lnFig. 5 I have shown a modified construe y tion of the pinions 29 and35 and toothed por tions of the rods 30 and 36. rhe pinioris'D roo and'35b are eccentric, and the toothed p'ortions 30h and 36 are in thisnstance made in warmste coe of the eccentric pinions,"with thetoothedportions h" and 36?' held in engagement therefthereby. Y n y 'loanextension 43 on the angle-lever 43 is1 with by the rolls 38". By meansof the eccentric pinions 29b and 35". I obtain a fast and slow motion ofthe lever 18. u A

1n Fig. 6, in addition to the parts shown in Fig. 1, l have shown someof the parts of the multiplier mechanism shown in Figs. 'Tand 8, whichis ot' well-known construction and fully shown and described in UnitedStates Letters Patent No. 413,369, of October'22, 1889, to whichreference is made. In-said Figs. 6,7,

:and 8, 38l is the auxiliary pattern-chain barrel of the box mechanism,mounted on the shaft 7 and carrying' the auxiliary patternchain ,392 AleverAO, pivotedat one end vat- `the upper end of a stand 41,'extendsover the auxiliary pattern-chain 39,'l and has pivotally attachedat itsouter end the upper end of a link 42. The lower end of the link 42 isconnected with one arm of a bell-crank lever 43, pivoted at 44. Theother arm of the bellcrank lever 43 engages with a collar 45, fast on arod 46 carryinga yokejj47, which engages the hub of a pin-wheel 48,adapted to slide on a rod' 49 and move into and out of engagement with astar` wheel 50, fast on a sleeve carrying the box pattern-barrel 7'. Asecond star-wheel 51l is operated by a pinwheel 52, which is adapted toslide on the rod vligand be movd outV of engagement with the star-wheel51 bya yoke 53 engaging the hub of said pin-wheel 52.. Said yoke 53 isfast on arod 54.4 Also fast on the rod 54isja collar 5 5, havinga notchtherein to receive the end of one arm 'of an angle-lever 56, pivoted at57..v 'The' other arm of ASaidfanglef-lever 56 is con'- nected by a link58 with 'an indicator-lever 59, pivoted at 60on astand 61.1V Thelindicatorlever 59 extends over aA series of indicators on the boxpattern -fzhai'n 7 and is controlled attached a spring `62', which actsto', move the angle-lever 43 on its`pivotal support, and through collar45, sliding rod`46, and yoke v47 move the pin-Wheel 48 out of engagementwith the star-wheel 50.l A spring 63' isattached lto an extension 56'onthe angle-lever 56 and acts to move the angle-lever 56 o'n its pivotalsupport and through the collar 55 and rod 54 and yoke 53 move thepin-wheel 52 out of engagement with the star-wheel 51, all in the usualand well-known way. Y

The operation of my improvements will be readily understood by'thoseskilledl inthe art.

I provide in each set of connections between.'

a single lever operated by the pattern-surface and the shuttlikboxes twocranks. The first crank, as above mentloned',being the vibratorgear 8a'nd receiving its motionfrom the driving-cylinders' 4 and 5,' is moved4through anb arc of substantially one hundred andeighty degrees intheusual manner and 'locked at its dead-center with respect to itsconnector 9. Through the movement of the first crank or vibrator-gear 8,connector 9, angle-leverlO, having a-n arm 31, and connector 30, saidconnector 30 having a toothed section thereon,30', adapted to mesh withand rotate a pinion 29, fast on shaft 27, the crank 26, fast on saidshaft 27, is also positively rotated or moved through an arc of a circleof substantially one hund red and eighty degrees at each movement of thevibrator-gear 8, thereby moving, through a connector 25 and lever 18,thegiveway mechanism and shuttle-boxes through a lift of `one cell. The twoconnector-pins of the connector 25 are held in substantial alinementwith the center of shaft 27, the second crank 26 being at what is termedits dead-center 'with respect to its connector 25. In case of thedesired movement of the shuttle-boxes for more than a single cell thenthe movement of the second vibrator gear or crank 8, through itsconnections with box v-lever 18, between the end thereof and the givewaymechanism, in a similar way, as above described, will compound themovement of said lever 18 to move the shuttle-'boxes 13 for more than asingle cell, as will be under stood.- A similar and independent movemento f the shuttle-boxes at the other end ot'` the loom may be obtainedthrough the vibratorgears 8, rigid vconnectors 9, and cranks andconnectors, as before described.

, I Wish it to be clearly understood that in my construction any weightor strain that may come on the boxes after the full move- 'ment of thevibrator-gear 8 is accomplished will I o0 their locked or dead-centerpositions by the 105 l vibrator-gears 8.

A box-movement of any number of cells may beobtained by the substitutionof as many compound levers for the lever 18 as may be required,.togetherwithv additional sets ot' ilo cranks and connectors. Each s'et ofconnections between the pattern-chain indicator-levefr and itscorresponding compound lever has therein two cranks, giving adouble-crank motion in each set of connections, as before dev15 scribed.

I have shown herein and particularly described my improvements combinedwith what is ordinarily termed the Knowles7 box indicating mechanism;but it will be understood 120 that my improvements may be adapted to beapplied to looms of ordinary construction provided with any well-knownbox indicating mechanism having two or more movable shuttlc-boxes atone'or both ends of the loom, and 1.25

my improvements may be used in connection with any ordinary box-motionmultiplier.
